Specification of Ilett'eis Patent.

Application filed September 22 1920. Serial No. 412,003.

To all whom. it may concern:

Be it known that I, JoHANNns DRAENERT, a citizen of the German Republic, residing at Nordring 41, Eilenburg, Germany, have made new and useful Improvements in Toothbrushes, of WlllCll the following is av specification, taken in connection with the accompanying drawing. I

lviy invention relates to a new anduseful tooth brush. More particularly it relates to tooth brush which has integral means tothe handle being preferably formed ofsome material as forexample celluloid, so that 1t,

or a portion of it, is transparent, permitting the reading of the advertising matter. My invention further relates to such a tooth brush in which advertising matter and the pills are both mounted within the handle.

My invention further relates to certain details of construction and combinations which will be more fully hereinafter'described and pointed out in the claims.

In the figures, in which I have shown one embodiment of my invention, the same reference numerals refer to similar .parts in the several figures. I I

Figure 1 is a plan view of my improved tooth brush, with the cap shown in its two positions.

Fig. 2 is a side elevation partly. broken away and showing advertising 'matter mounted in the handle. i

Fig. 3 is a plan view similar to Fig. 1 except showing advertising matter as in Fig. 2. 1

Fig. 1 is a detail horizontal section, on

an enlarged scale showing the cap with its pivoting and locking mechanism.

- It is common practice to use a tooth brush with some dentifrice contained in a separate tube, bottle or box. This requires the handling of at least two articles. To a traveler this is a particular annoyance as it requires him, each time that he moves, to gatherup and transport an additional article. I,

atente Jan, 1921.

In my invention I so form a tooth brus I that pills'of concentrated mouth, washer other dentifrice, may be located directly within the tooth brush, and preferably with in the handle. A person, and particularly a traveler,fwhen he packs his tooth brush made in accordance 'with my'invention,

knows that he also has [his dentifrice- My invention, may be embodied in diifen ent forms. I have shown by way of example a toothbrush '1 havin the bristles 2 and ham dle Fig. 1. This andle forined'hoh lowso asto make a compartment or reservoir. 4. within which the dentifrice, as for example the pillsf3,o'ofccncentrated mouthwash, 1

- Ontheen'd 6 ofthe handle, I mount a cap 7 bypassing a screw 8 through the cap and lettingthe screwfthreaded portion .9cof the screw be embeddedwithinfithe.endfi of the handle. Preferably, though not necessarily,

I place" any suitable sealing. material. 10 over the head .11 of the screw! The .unthreaded portion12 of the screw acts asa pivot upon whichthe cap 'Zrocks. I

Thecap 7 is locked tothejend Go f the; handle in any suitable manner. Preferably I provide the cap 7 with a'cha'mber '13 within which is mounted the screw 14 having a stem .15, head 16,.anda screwthreadedpora 'tion" 17. Themale threads '17 upon the screw 14 cooperate with the female screw threads 18 in the throat 19 of the end6.

To look the. cap 7 in position, it is merely necessary to rock'the cap upon the pivot I 8 until themale screw threads 17 register with the female screw threads 18 in thethroat 19. :Bvthen rotating the head 16 these male and femalev threads 17 and 18 are. caused to cooperate and lock the cap ,7

inits closedposition as shownin Figs; 4;

and 3, and in full linesin Fig.1.

To fill the compartmento'r reservoir' l into the compartment 13. As soon asthe with the pills 5 or other dentifrice, itis merely necessaryto unscrew the screw 14 to release the male and female screw threadsv 17 and 18 permitting the screw to be raised 7.

, p end of the screw '14 is free from the throat 19 the cap 7 can be rotated upon the pivot 8 so that access may be had to the chamber a,

. tooth brush is preferably formed of celluloid with the exception of the bristles 2 and the pivot pm 8. This prevents any part rusting and insures that it will always be in a sanitary condition.

A mere glance at the handle, without opening the cap 7 will immediately disclose whether or not there are any pills 5 within the handle, and whether or not their number is so reduced that the supply should be replenished.

My invention is also adapted for advertising purposes whether or not pills or other dentifrice are used.

I have shown for example in Figs. 2 and 3, a tooth brush in all respects the same as that shown in Fig. 1 except that in these figures, a strip of paper or other suitable medium 20 is mounted within the chamber or reservoir 4 and contains advertising matter 21 which can be clearly read through the handle. Preferably this advertising matter is displayed both on the back 21 and on the face 22 of the brush. Preferably, though not necessarily, the pills 5, 5 are also used in this form of my invention.

Any suitable means may be employed for inserting the advertising matter within the handle. I may for example mold the handle of celluloid, or any other suitable material, leaving the front open so that the advertising matter may be inserted. The front can then be closed with the face plate 23 preferably of celluloid. This faceplate can be added by any well knownmeans such as by using any suitable solvent as ether, or some similar material. To all intents and purposes the face plate 23 is integral with the handle and cannot be distinguished from it except by close scrutiny.

Having thus described this invention in connection with thereof, to the details of which I do not desire to be limited, what is claimed as new illustrative embodiments 7 and what is desired to secure by Letters Patent is set forth in the appended claims.

hat I claim is 1. The combination of a celluloid tooth brush having a hollow handle in which pills of concentrated mouth wash or other dentifrice and advertising matter may be placed, a pivoted cap on the end of the handle to close the opening in the handle and a screw to lock the cap in its closed position.

2. The combination of a tooth brush formed of a single rigid member having the bristles of the brush mounted on one end of said-rigid member, the other end being the handle of the tooth brush and formed hollow to act as a compartment or reservoir for pills of concentrated mouth wash, a cap pivoted on the end of the rigid handle and adapted to close the end of said handle, and means to lock the pivoted cap in its operative position closing the end of the hollow handle.

8. The combination of a tooth brush formed of a single rigid member having the bristles of the brush mounted on one end of said rigid member, the other end being the handle of the tooth brush and formed hollow to act as a compartment or reservoir for pills of concentrated mouth wash, a cap pivoted on the end of the rigid handle and adapted to close the end of said handle, and means carried by and moving with the piv oted cap to lock the pivoted cap in its operative position closing the end of the hollow handle.

4-. The combination of a tooth brush formed of a single rigid member having the bristles of the brush mounted on one end of said rigid member, the other end being the handle of the tooth brush and termed hollow to act as a compartment or reservoir for pills of concentrated mouth wash, a cap pivoted on the end of the rigid handle and adapted to close the end of said handle, the end of the handle being provided with screw threads, said pivoted cap being provided with a chamber, a locking screw rotatably mounted. in said chamber and adapted to cooperate with the screw threads in the end of the handle, and means to prevent the disengagement of the locking screw fromthe pivoted cap.
